[can't install the universal version on my Huawei Mate 40 Pro]

@maxmp from the very beginning, I wanted to install the uni build which i downloaded from your website because I dont have GMS on my phone. however I couldn't install it due to the reason I mentioned above. then i installed the google play build on my Mate 9 and transferred it to my Mate 40 and it is working well. however, as you know my mate 40 doesn't has GMS and i cant buy this app from google play when the trial is expired. so i want to install a uni build on my mate 40 pro. btw, is this app available in Hauwei AppGallery? if so maybe need to change my phone region to overseas

I download the latest universal version and tried to install on my Huawei Mate 40 Pro. however, the phone prompted that it's a fraud app and can't proceed the installation. why is that?
